“…Its solubility is due to the presence of the lactam amide group which provides both hydrophobic and polar characteristics. PVPs are mostly used as vesicle transporters, film formers, binders, and detoxifiers in the pharmaceutical, cosmetic, food, and adhesive industries. Recently, PVP has been introduced on to cellulosic materials via NVP graft‐copolymerization in order to combine the properties of PVP and cellulose.…”

Lactam groups were introduced onto the backbone of hydroxyethyl cellulose (HEC) to modify properties, such as solubility in organic solvents and solution viscosity and to introduce possible antibacterial activity. Functionalization was achieved using 1-(hydroxymethyl)-2-pyrrolidinone (HMP), and the functionalization reactions were investigated using NMR spectroscopy. The covalent attachment between HEC and HMP was confirmed using 1 H-13 C correlated NMR experiments. Degrees of functionalization were calculated using integrated 13 C NMR spectra, with values of up to 0.9 being demonstrated on the primary alcohol functionality of HEC. The functionalized HECs showed markedly different properties to unfunctionalized HEC, including the ability to swell considerably in water. Functionalized HEC displayed increased thermal stability and reduced solution viscosity compared with unfunctionalized HEC. Moreover, functionalization altered the bacterial adhesion characteristics compared with unfunctionalized HEC.
